US Classification:
422221, 422219, 422214, 422232, 422236
Abstract:
An apparatus provides for increased feed throughput without loss of conversion or selectivity by increasing the catalyst volume in a final reactor of at least three reaction zones. The catalyst volume of the final reactor may be larger because the inner and outer screens that define a radial flow bed are extended. A low LHSV is maintained by increasing the catalyst volume in the final reactor.

US Classification:
96152, 55518, 422218, 422239
Abstract:
An apparatus is shown for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by louvers that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures. And the apparatus includes baffles to inhibit erosion of the particles by redirecting the inlet gas flow.
Optimizer Hydraulic Enhancement Using Milled Plate
A radial flow reactor fluid duct distribution apparatus is presented. The apparatus includes a plate of sufficient thickness to impart strength to the fluid flow duct and is milled to have narrow slots allowing fluid to flow through the plate, while preventing the passage of catalyst through the plate.

US Classification:
422211, 422218, 422219, 422220
Abstract:
A radial flow reactor design is presented. The reactor has individual and interchangeable screens that are arrayed circumferentially around the inside of the reactor. The reactor includes a plurality of screens held out from the reactor wall to form a circumferential screen, with channels defined between the reactor wall and the circumferential screen.

Abstract:
A secondary containment system is used with a screenless reactor. The secondary containment system includes a screen sized to prevent the passage of catalyst particles, and is affixed to the screenless reactor with supports to hold the screen a desired distance from the reactor.
An apparatus is for directing a fluid into a radial reactor is and which maintains a bed of solid particulate material within a reactor. The apparatus comprises a duct for directing fluid into a reactor and has a screenless face for the egress of the fluid, while providing for the retention of solid particles.

Abstract:
An apparatus is presented for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with openings disposed within the partitions. The openings are covered by louvers that extend above the edges of the openings to prevent solid particles from spilling through inlet openings, and the design prevents the loss of particles through the openings during cooldown of the apparatus.
